The government of Sri Lanka has temporarily blocked access to several social media services following deadly explosions that ripped through the country, killing at least 207 people and injuring hundreds more.

Eight bombings were reported, including during Easter services at three churches, on the holiest weekend of the Christian calendar.

In a brief statement, the Sri Lankan president’s secretary Udaya Seneviratne said the government has “decided to temporarily block social media sites including Facebook and Instagram,” in an effort to curb “false news reports.”

The government said the services will be restored once the investigations into the attacks had concluded.

Nalaka Gunawardene, a science writer and Sri Lankan native, confirmed in a tweet that Facebook-owned WhatsApp was also blocked in the country. Others reported that YouTube was inaccessible. But some said they were able to still use WhatsApp .

It’s a rare but not unprecedented step for a government to block access to widely used sites and services. Although Sri Lanka’s move is ostensibly aimed at preventing the spread of false news, it’s likely to have an inhibiting effect on freedom of speech and efforts to communicate with loved ones.

Sri Lanka, like other emerging nations, has previously battled with misinformation. The government has complained that false news shared on Facebook has helped spread hatred and violence against the country’s Muslim minority. Other countries like India say encrypted messaging app WhatsApp has contributed to the spread of misinformation, prompting the social media company to add limits to how many groups a message can be sent to.

Iran and Turkey have also blocked access to social media sites in recent years amid protests and political unrest.

Sri Lanka’s prime minister Ranil Wickremesinghe has described the explosions as a terrorist incident.
